The synchrophasor technology has become focus of many theoretical, conceptual and practical studies lately due to an increased opportunity to improve power system reliability and security through enhanced monitoring, protection and control. The paper provides a survey of signal processing, communication and networking issues surrounding this topic so that professionals from related areas can benefit...
Frequency, amplitude and phase angle are three major parameters describing a stationary sinusoidal signal. In power system, many applications such as the state monitoring and protective relaying measure these parameters as performance indices or critical variables in the algorithm criteria respectively. This paper proposes a new method for estimating the power system frequency and phasors in real...
This paper presents a new test methodology for evaluating the security and dependability of protective relay operations. A discussion of the important impact of relay security and dependability on power system reliability especially during cascading events and unusual operating conditions is presented. The new test methodology includes comprehensive power network modeling, generating test scenarios...
Transmission line protective relays are assuring normal operation of power system by automatically isolating faulted sections. Different disturbances in power system could affect relay behavior and may result in relay misoperation or unintended operation. This paper explores various aspect of the performance analysis of existing protective relays. Three categories of solutions are discussed: 1) relay...
